Enemy Grid / alternative name plate organizer for 3.3.5?

Is there any alternative addon that makes dotting easier for Wlocks, Mages, Priests?

Any addon that takes enemy name plates and organizes them would be sufficient.

There is no way to organize nameplates except for overlapping / non-overlapping.

The only visually helpfull thing you could do is to have DoT timers on nameplates and/or timer for active dots.
